Belts and rack and pinions have got a few common benefits for linear gearrack china linear motion applications. They’re both well-founded drive mechanisms in linear actuators, providing high-speed travel over incredibly long lengths. And both are generally used in huge gantry systems for material handling, machining, welding and assembly, especially in the auto, machine device, and packaging industries.

Timing belts for linear actuators are typically made of polyurethane reinforced with internal metal or Kevlar cords. The most common tooth geometry for belts in linear actuators is the AT profile, which has a big tooth width that delivers high level of resistance against shear forces. On the driven end of the actuator (where the motor is usually attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a flat pulley simply provides assistance. The non-driven, or idler, pulley is often used for tensioning the belt, although some designs provide tensioning mechanisms on the carriage. The kind of belt, tooth profile, and applied stress force all determine the power which can be transmitted.
Rack and pinion systems found in linear actuators consist of a rack (also referred to as the “linear gear”), a pinion (or “circular gear”), and a gearbox. The gearbox really helps to optimize the quickness of the servo electric motor and the inertia match of the system. The teeth of a rack and pinion drive can be directly or helical, although helical teeth are often used due to their higher load capacity and quieter operation. For rack and pinion systems, the maximum force that can be transmitted can be largely dependant on the tooth pitch and the size of the pinion.
Our unique knowledge extends from the coupling of linear program components – gearbox, motor, pinion and rack – to outstanding system solutions. You can expect linear systems perfectly designed to meet your unique application needs in terms of the soft running, positioning accuracy and feed pressure of linear drives.
In the research of the linear movement of the gear drive system, the measuring platform of the apparatus rack is designed to be able to gauge the linear error. using servo electric motor directly drives the gears on the rack. using servo engine directly drives the apparatus on the rack, and is dependant on the movement control PT point mode to realize the measurement of the Measuring range and standby control requirements etc. Along the way of the linear motion of the gear and rack drive system, the measuring data is certainly obtained utilizing the laser interferometer to measure the position of the actual movement of the gear axis. Using the least square method to solve the linear equations of contradiction, and to expand it to any number of times and arbitrary quantity of fitting functions, using MATLAB programming to obtain the actual data curve corresponds with style data curve, and the linear positioning accuracy and repeatability of equipment and rack. This technology could be extended to linear measurement and data analysis of nearly all linear motion mechanism. It can also be used as the foundation for the automatic compensation algorithm of linear motion control.
Consisting of both helical & straight (spur) tooth versions, within an assortment of sizes, components and quality levels, to meet nearly every axis drive requirements.

These drives are ideal for a wide selection of applications, including axis drives requiring exact positioning & repeatability, traveling gantries & columns, pick & place robots, CNC routers and materials handling systems. Heavy load capacities and duty cycles can also be easily dealt with with these drives. Industries served include Materials Handling, Automation, Automotive, Aerospace, Machine Tool and Robotics.
